To all whom it may concern:

Be it known that we, HENRY NICHOLS and CHARLES G. NrcHoLs, residing in Appleton, in the county of Outagamie and State of Wisconsin, have invented new and useful Improvements in Devices for Discharging Liquids, of which the following is a description, reference bein had to the accompanying drawings, whic are a part of this specification.

Our invention relates to improvements in devices adapted to be employed in tanks or elsewhere where there is a varying height of" the water or liquid to be discharged, the device being adapted automatically to change I its position and to take and maintain a position with constant reference to the height of the liquid being discharged, the device embodying incidentally a liquid-purifier in the nature of a strainer or filter adapted to separate and remove from the liquid all solid or foreign substances and exclude them from passing through thedischarging device.

As our improved device will be more likely to be used chiefly in connection with tanks for filtering and discharging water therefrom, we have shown it in connection with tank, thereby illustratin the use to which the device can be put an in such manner as it is likely to be chiefly used.

The invention consists of the device, itsv parts and combinations of parts, as herein described and claimed, or the equivalents thereof.

In the drawings, Figure 1 shows a tank in vertical section having a supply of water therein with our improved device therewith, showing the manner of mounting it and of its use. Fig. 2 is a plan of that part of our. improved device that is directly connected to the supporting-wall of the tank, with the part that forms a movable connection therew1th. Fig. '3 is a section of the parts formmg the movable joint in that art of the device shown in plan in Fig. 2. ig. 4 is a seccharging device, the rod or ball for attaching oat thereto being, shown in full lines; and Fig.5 is a central vertical section through the structure shown in Fig. 4.

In the drawings, A represents a tank, of a form with which our improved device may be employed, No means are shown for supplying the tank with liquid, but this may be y any suitable or desirable means what- This intake filter-port is advisab B is the port of an overflow-pipe adapted to prevent the undue filling'of the tank with water or liquid. I

3 is a pipe leading from the tank to a pump or other means for forcibly withdrawing the water or liquid from the tank. .The inner and lower end of this ump-pip'e 3 term nates in a head 4, in which it is fitted and held detachably by a screw-thread connection 5. This head 4 is provided with a rigid neck 6 and base-piece 7, the base-piece being adapted to be placed against and secured to the side of the tank by means of nails or screws. This head 4 is rovided with a liquid-chamber 8, from which the pi e 3 leads; and a tubular right-angled or 'ebow-joint piece 9 is fitted revolubly in this head-piece 4 in seats 10 and 11 therefor at the res ective sides of the chamber 8, through w ich the tubular joint-piece 9 extends transversely medially. The tubularjoint-piece is provided with orts 12 opening through its side walls into t e chamber 8. The joint-piece-9 is also rovided with an annular flange 13, and pac ldngs 14 around the joint-piece 9 fit against theflange on both sides thereof and fill the annular space between the j ointpiece 9 and, the surrounding wall of the stuffing-box 15, formed on the head 4. A gland 16 about the joint-piece 9 is held to the stuffing-box by screws and compresses the. packing within the stuffing-box. By the construction just described the j oint-piece 9 is fitted and held water-tight and rotatably in the head 4 in such manner that it discharges into the chamber 8.

A tubular arm 17 is coupled onto the jointpiece 9 conveniently and advisably by means of the smaller tubular elbow-joint 18, which f the swinging tubular arm 17 has an intake port comprising the filter 19. (ShowninFlg. 1 and illustrated in detail in Figs. 4 and 5.)

ed with metal convex circular heads 20, held toeach other by a number of binding-rods 21, fixed in terminal rings 22, the rings being placed against and secured to the marginsof the heads 20, whereby the skeleton of a cylindrical chamber isformed. A sheet-metal screw-threaded terminally. At. its outer end. 7

yconstructsieve or screen 23, secured to the heads 20 at its edges and passing around the rods 21, forms thesides of the filter, whereby water or liquids may pass freely from the exterior into the chamber. Longitudinally of this I chamber and centrally thereof there is a duct 24, formed of two sections of pipe 25 25, connected together centrally by a T tubularhead 26, in which the inner ends of these pipes are secured by screw-thread, the outer ends of these pipes 25 passing, respectivel through the heads and being secured t erein and thereto by 'screw caps 27 turningthereon. The tubular swinging arm 17 enters the filterchamber throu h the screen side thereofand is screw threa ed into the cross-head 26, whereby this swinging arm opens into the duct 24. The pipes on'the T-head 26 are provided in their sides with transverse slots 28 opening into the-chamber of the filter. The interior of the filter-chamber is advisably filled with some filtering or purifying material, as preferably charcoal 29, through which ghgcal water or liquid may percolate and be clari- The filter intake port 19 is to be automat ically located and held in the water or liquid at a little distancebelow the surface thereof,

so that it will be constantly supplied with the water or liquid at some distance above the bottom, where the sediment,'if any, isfound, and a little below the surface, on which any floating foreign matter may rest, and for this pur ose a float 30 is attached to the filter in suc relation thereto that the float restin on the surface of the water will support the lter may be made of heavy elastic wire, so thatv its ends can be sprung into the sockets in the caps 27 and, if desired, can by reason of its elasticity be readily detached therefrom. What we claim as our invention is 1. A. device for discharging liquid from re- .ceptacles, comprising a swinging tubular arm supported pivotally within thereceptacle to a non-swinging discharging-tube, a laterally-expanded chamber on the free end of the swinging tubular arm and opening thereto and having a port to take liquid from the receptacle, a bail having its'separated ends pivoted in horizontally-exposed ends of the chamber, and a closed hollow float semovably with reference to and at a distance below the float.

2. In combination, a liquid-holding receptacle, a -discharge-pipe entering the receptaole and secured to, the wall thereof medially of its height, a swinging tubular arm pivoted to and discharging into said wall-attached pipe, a laterally-expanded filtering intakeport chamber secured to and forming the free end of the swinging tubular arm, socketed members on the horizontally-exposed ends of the intake-chamber, an elastic bowed bailthe ends ofwhich enter pivotally the sockets of the socketed members of the chamber, and'a closed hollow float secured medially to the bail adapted to float on the suface of the liquid above the filtering-chamber, and to support 'suspendedly the intake-chamber in the liquid at a'distance below the surface of the liquid v 3. In combination, a liquid-holding recep tacle, a discharge-pipe entering and secured to the receptacle, a swinging tubular arm pivoted and discharging in said secured pipe,

a drum-like filteringintake-port chambersecured to and forming the free end of the swinging tubular arm, a bowed hail the ends of which are pivoted in the horizontally-exposed ends of the intake-chamber, a closed hollow float secured medially to the bail and adapted to float on the surface of the liquid at a distance above the intake-chamber, and

'to maintain the intake-chamber in the liquid at a constant distance adjacent to but below its surface and movable with reference to the float.
